The correct option is A True
Answer is A.
We can say that objects that are charged contain unequal numbers of protons and electrons. Charged objects have an imbalance of charge - either more negative electrons than positive protons or vice versa. And neutral objects have a balance of charge - equal numbers of protons and electrons.
As the atom looses electrons to become positively charged, the total mass of the body gets reduced slightly. Hence, the statement is true.
